INSTALLATION OF SYSTEM INSTRUCTIONS

PREPARATION OF SUBFLOOR• Wood sub�oor must be of suf�cient soundness, structural

strength, and physical rigidity to withstand, without de�ection or movement, the maximum surface condition to which the �nished �oor will be subjected.

• Wood sub�oor must be a minimum of 5/8” plywood.

• Sub�oor should be installed to provide a 1” fall in an average 4’ deck (recommended).

• All slider and door thresholds, jambs, posts, deck edges, scuppers, and fascia must be installed with galvanized metal �ashing, caulked and primed, in accordance with building code requirements.

• Install Desert Crete Metal Nosing with primer on all deck edgings at no less than 3/16” vertical rise (recommended).

• Must comply with all applicable building code requirements in type and installation.

METAL LATHING• After all required �ashing is in place and primed with Desert

Brand Bonder 480, thoroughly secure hot-dipped galvanized metal lath (2.5 lbs. per sq. yd.) upon the wood sub�oor.

• Lap metal lath sheets together at a minimum of 1”. Lap all metal �ashings with lath at ¼”-½” from the vertical riser of the �ashing.

• Use minimum 16 gauge galvanized staples with 7/8”-1”crown by 5/8” leg. Place 24 staples per sq. ft., spaced not to exceed one staple per every 6 sq. in.

• Metal lath must be secured, without de�ection, upon wood sub�oor using staples no greater than 1” apart.

FIRST DESERT CRETE BASE APPLICATION• Trowel thoroughly mixed Desert Crete Base (mixed with Liquid

Polymer), Level Max 20/30 (mixed with diluted Polymer 550), or Polybase (mixed with water) into the metal lath.

• Make sure any holes in the lath are �lled to the top.

• Allow to dry completely before proceeding (approximately 2-3 hours depending upon conditions).

FIBERGLASS AND BONDER 480 APPLICATION• Apply ¾ oz. per sq. ft. �berglass matting to the �rst Desert Crete

application.

• Lap �berglass 2” over �ashings and 1” at seams. Cut �berglass to �t around posts and drains.

• Generously apply Bonder 480 into �berglass matting using a ¾”-1” nap roller covering approximately 50 sq. ft. per gallon. Bonder 480 is designed to soak through the matting adhering it to the Desert Crete base surface.

• Allow to dry thoroughly before proceeding (approximately 24 hours depending upon conditions).

SECOND DESERT CRETE BASE APPLICATION• Trowel a second application of Desert Crete base product over

the dried �berglass and Bonder 480 to a minimum thickness of 1/16” (see image 1.1 on reverse side).

• Allow to dry completely before proceeding (approximately 2-3 hours depending upon conditions).

DESERT CRETE TEXTURE APPLICATION• Thoroughly mix Desert Crete Texture (50 lb. bag) with Desert

Crete Liquid Polymer (1¼ gal.).

• Apply using a pneumatic hopper gun. The recommended air pressure for application is between 30-40 psi.

• Wait 5-10 minutes before knocking down the splattered texture with a steel trowel.

• Allow 1-2 hours drying time before proceeding.

DESERT BRAND SEALER APPLICATION• Apply two coats of pigmented Desert Brand CMFPS.

• Allow approximately 2-3 hours dry time between coats, depend-ing upon temperature and humidity.

• Periodically maintain system by applying a coat of pigmented Desert Brand CMFPS.
